Couplings

Zero-Max Overhung Load Adaptors protect shaft seals in hydraulic systems. They provide an intermediate mounting platform between a motor and pump to absorb both internal and external stress conditions in a hydraulic system.

Control-Flex® couplings from Zero-Max are designed for encoder applications. Where speed and positioning feedback in a system is critical, Control-Flex couplings help minimize a system’s reaction forces for more precise and repeatable operation and longer life. Designed with a unique parallel linkage-style flexible disc, Control-Flex provides radial flexibility to reduce reaction forces such as side loads on shaft bearings and seals that can be caused by shaft misalignment.

COUNTEX® is a three-piece, torsionally stiff coupling which was specifically developed for the zero backlash demands of measuring and control applications. The double-cardanic operating principle of COUNTEX® minimizes the restoring forces in a compact design ideal for ac-comodating large shafts and short DBSEs.

ServoClass Couplings from Zero-Max feature fail safe clamping hubs that provide maximum torque transmission in high speed applications. Without the use of keyways, ServoClass Couplings are designed, manufactured and tested to provide superior shaft engagement in servo motor applications at speeds up to 10,000 rpm.

R+W has expanded upon its proven design of vibration damping drive shafts, series EZ2, with a new miniature design, size 5. The new size 5 shafts feature customer specified lengths and bore diameters, along with fully split clamping hubs for easy drop-in mounting. Speeds in excess of 5000 rpm can be achieved without any intermediate support bearings required.

Offset Couplings from Zero-Max reduce space requirements for parallel offset shafts in large system applications. These couplings provide machine designers with an option for reducing overall machine size and footprint. Compact in design, Schmidt Offset Couplings transmit constant angular velocity and torque in a wide range of parallel shaft misalignments. Handling high amounts of parallel offset up to 9 inches, available with torque capacities up to 459,000 in-lbs.

Zero-Max’s new 28-page brochure features a complete line of keyless locking devices for shaft to hub connections in a power transmission system. These devices are ideal for positioning and locking shaft components. They provide the best solution where keyways and tapers can weaken or cause excess wear to the shaft. Zero-Max keyless connections design benefits include zero backlash and superior concentricity. They mount and dismantle in less than 10 seconds and have fewer screws than alternative products.

Miki Pulley announces introduction of its Step-Flex Coupling for direct sale to OEMs in North America. The Step-Flex is an altogether new class of shaft coupling. This design was conceived to eliminate resonance in stepper motor ball screw assemblies. The innovative two part elastomer element combination dampens vibration caused by the actuator carrier struggling to find its home position by making small adjustments in rapid sequence.

Motion system designers have a new option to arrest electrical current. In addition to their primary function, Zero-Max CD® couplings are designed with composite flex elements that are non-conductive. The flex element designed into Zero-Max CD couplings provides electrical insulation while protecting mechanical components from system overloads. CD Couplings do not pass electrical current through the coupling.
